Could stories with images be uploaded as .MHT or .MHTML single file webpages?
Sorry, but not possible. There are many reasons why such a format cannot be supported.
The text in our system lives in a text database, so it's not files that can be just put there. The images have their own server too.
When we post, we upload the images that you submit to the image server which generates the {img } tags according to your instructions (left, right or center) and then we replace the [[img]] tags in the text with the tags generated by the image server.
Due to the vast array of viewing devices (computers with varying screen sizes, phones, tablets) and viewing methods (directly on the website, or in an EPUB reader), and user preferences regarding story display, your code would probably not work as you expect it everywhere. Our generated html code would produce the code that suits the readers viewing devices and preferences.
